[Jon can you verify that the email address is correct ?]
Hi Jim,
I do not have the same setup as you do but the debugging info indicates
a problem with line :
if ((dpy != XtDisplay(w)) || (event->xany.window != XtWindow(w)))
Not being able to reproduce your problem, and not really knowing this
function very well I would
try the following line instead :
if ((dpy != XtDisplay(w)) || ( event = NULL ) || (event->xany.window
!= XtWindow(w)))
Can you also check the version of X windows on the sgi machines. Is it
possible that it is X11R5 ?
I am also attaching the version of Vendor.c with the above fix for the
0.90.0 version of lesstif.
Please tell us if this works for you.
CP
